IMPRQVHMENT IN coN'DENsnRs.

To all whonrtft may concern i i A e Beit known' that L'THoMAs SHAW, ofthe city and county of Philadelphia, Pennsylvanimhave invented a -new and improved Method of Condensing the Exhaust- Steam of High-Pressure Engines; and I hereby declare drawing, and to the letters of y reference marked there-` on.- i

My invention eonsistsin `"coune'eting a'condensing` chamber Withthe exhaust-pipe of the engine, in such a manner that thefirst, rush of steam shall clear the chamber of air and \vat'er,f(tliat the air-pump may be dispensed with, and the apparatus sim pliied and cheapcned 5)" also, in the arrangement of injector and valves, in Vthe* manner and `for the purpose as hereafter described. j A A In order to enable others'to use and practise my inoperation. A i i On reference to the accompanying drawing, which forms part of thisV speciicat-iomthe lsketch'represents a longitudinal vertical section, through the centreof A condenser,`of which a is a `metaltube, provided withA t A` sockets b and c. Said tube 'a has a partition across' ohe end, (l, provided with an` aperture covered by a gum-valve, g,'and lined in theinteriorwith a woodinthe middle part au injectingftube, ffbored with small apertures on the inner 'end for the injection of a spray of Water, and with a common valve, c', secured in'socket h, opening inward, all for the purpose as hereafter described. p f

" The socket b is-cohnected by a pipe with the'exi A haust part of the engine, and the socket c is connected`- bya pipe with a tank for vthe collection of hot water from1 the condensed steam; "and the socket h is conthe purpose of conveying cold, water to the injectingtheffollowing tc? be a full, clear, and exact description e of thesarne, reference being hadto the accompanying vention, I willv proceed to describe its construction and' tube, e, (as anon-conductorof heat,) and has inserted 'i nec'ted `by 'a pipe with a` pump, orA elevated tank, for f A The Schedule referred to in these Letters Patent and making ,part of `,the nahme. v

A l A tube lf,'under a pressure one-half less than the highest pressure of the exhaust-steam.

The exhaust-chamber is made sniiioiently small,`

that the first part of the exhaust is'ce'rtain to blow `through it, in order to eject the air and water. The condensing-chamber works in this wise: The steam from the exhaust rushes into and through' -the chamber, and all that passeso'ut of valve g is not allowed toreturn by reason of said valve; and in the actof rushing through the chamber, the air and Water previously contained therein is ejected throughnthe valve y', so long as there is l,any hpressure in said cham'- ber.

the pressure within the chamber, and the cold water is prevented from entering said chamber, so long as thepressure ot' steam is above that of the column of water,whic11, however, is for a very temporary period,

only during the first 'ash of steam, after whiclrthe injector spurts, and condenses the remaining steam, when the operation is repeated, as before described. i

It will be observed that the apparatus need not be of theA precise form and shape here shown, but` can be considerably modified without any alteration inthe result. A

The object of the invention is to furnish a cheap, re-

liable condenser for highlpressure engines, in order yto increase theirpower, and to allow theeXhaust-steam to be forced back in the boiler in the shape of hotwater, to save all thatl heat, and to have the engine operated with less noise.

What l claim, and desire to secure by Letters Ilat- `ent,-is

The construction of the described condenser on high- `pressnre engines, in the manner substantially as set v forth.'
